(1)当须要重复使用的测试状况,能够用shared_examples("describe") do end提出来,在须要使用的地方可使用it_behaves_like "describe"复用,代码写在controller_spec.rb文件中ruby
(2)能够将大量重复使用的代码,单独提出来,放在spec/support/下放在Module中,并在spec/spec_helper.rb文件中的RSpec.configure块中,加入config.include Moudle, 或者直接在spec/support下或子文件夹下写个rb文件,spec_helper.rb会自动require,以下代码:app
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }测试
(3)可使用自定义匹配器简化代码,例如登录功能:ui
spec/support/matchers/require_login.rburl
RSpec::Matchers.define :require_login do |attribute| match do |actual| expect(attribute).to \ redirect_to Rails.application.routes.url_helpers.login_path end failure_message_for_should do |actual| "expected to require login to access the method" end failure_message_for _should_not do |actual| "expected not to require login ro access the method" end description do "redirect to the login form" end end
使用:code
expect(response).to require_login
